Application March 17, 1939, Serial No. 262,488 In Great Britain April28, 1938 25 Claims. (01. 12-123) This invention relates to machines foroperating on shoes, and is herein illustrated as applied to a machinefor lasting the heel ends of shoes, the machine being one of the sametype as disclosed in United States Letters Patent No.

1,949,539, granted on March 6, 1934 on an application of J Gouldbourn,F. Ricks and W. T. B. Roberts. It is to be understood, however, that theinvention is not limited to machines of that particular type and that insome of its aspects also it is not limited in utility to lastingmachines.

A machine of the character disclosed in the above mentloned LettersPatent comprises a heel 151 band for embracingand clamping an upperabout the heel end of a last, wipers for wiping the margin of the heelend of the upper inwardly over an insole or heel-seat piece on the last,and a jack which is'mounted to swing in a direction lengthwise of thelast from an initial work receiving position to present the heel end ofthe last and upper within the heel band prior to the starting of the.power operation of the machine, the jack including a post which is alsomovable upwardly to carry the shoe into contact with a 25 holddown whichdetermines the position of the shoe heightwise relatively to: thewipers. Such a machine is sometimesused for lasting the heel ends ofshoes, such as. some kinds of stitchdown shoes, the uppers of which areloose on their lasts, or atall events have not been previously subjectedto the usual assembling and pullingover operations,.when the work ispresented to the machine. Under those conditions it is customary for theoperator to adjust the heel end of the upper heightwise relatively tothe last and to maintain it at the correct height by holding it with hisfingers in locations near the forward end of'the heel seat until hestarts the power operation of the machine. In order to relieve the 405operator of the necessity of thus holding the upper until the heel bandassumes control of it, which it is sometimes dirficult or inconvenientfor him to do, the present invention, in one aspect, provides novelmeans for clamping the upper to maintain it in proper adjusted relationto thelast. A's herein illustrated, such clamping means comprises anauxiliary heel band arranged to be positioned between the main heel bandand the upper during the lasting operation, and

mechanism supported on the jack for applying the auxiliary band inclamping relation to the upper prior to the work-presenting movement ofthe jack. To permit this hand to be main.- tained in proper relation tothe upper, the construction herein shown is further such that the bandand the mechanism for'applying it to the .shoe are so supported as topartake of the upward movement of the jack post as well as the swingingmovement of the jack, and also to partake of certain tipping movementsand bodily lateral movements of the work which, in a machine of theillustrated type, the operator may effect to adjust the work in properrelation to the lasting instrumentalities. The machine herein shown isalso provided with novel means for locking the auxiliary band inclamping relation to the upper and for thereafter releasing it as thejack returns toits starting position after the lasting. operation.

In accordance with a further feature of the invention, the mechanism forapplying the auxillary band to the shoe comprises novel means wherebythe band is first moved lengthwise of the shoe into clamping relation tothe upper at the extreme end of the shoe and is then forced inwardlyinto clamping relation to the upper at the sides of the shoe. For thispurpose the construction shown comprises levers which are connected tothe ends of the band and, by depression of a treadle, are swung firstlengthwise of the shoe and then laterally of the shoe, the swinging ofthe levers laterally of the shoe resulting from resistance of the shoeto the movement of thelevers lengthwise thereof. More particularly,

these band-applying levers are thus operated by the movement of a thirdlever connected to the treadle, this third lever being associated with atoggle deviceon which it fulcrums in its movement to swing theband-applying levers length- Wise of the shoe and which is yieldablethereafter to effect the movements of the band-applying levers laterallyof the shoe. Provision is also afforded, by reason of the normal shapeof the band and its resiliency, for applying it in clamp ing relation tothe upper at the sides of the shoe first in locations at substantialdistances from the edge .of the last bottom and then progressivelynearer the last bottom, as further insurance that the upper will beproperly clamped without the presence of any objectionable wrinkles. Inaddition to maintaining the heel-end portion of the upper in properadjusted relation to the last, the auxiliary band serves to conform theupper smoothly and tightly to the contour of the last before it issubjected tothe heavier conforming pressure of the main band, and thusassists in the proper shaping of the upper. It will be recognized thatwith respect to the auxiliary band herein shown and themechanism forapplying it to the shoe, the invention in certain of its novel aspectsis not necessarily limited in utility to a machine in which there isalso another band to operate on the shoe.

The above and other features of the invention, including various noveldetails of construction and combinations of parts, will now be moreparticularly described with reference to the accompanying drawings andthereafter pointed out in the claims.

In the drawings,

Fig.1 is a View in left-hand side elevation of a portion ofv a machinein which the invention is embodied, showing the auxiliary heel band inclamping relation to the heel end of a shoe, parts of the structurebeing broken away;

Fig. 2 is a View mainly in front elevation, on an enlarged scale, of aportion of the structure shown in Fig. l with the parts in the samepositions as in Fig. 1 but with the position of the shoe indicateddiagrammatically by broken lines;

Fig. 3 is a view similar to the upper portion of Fig. 2, but showing theauxiliary heel band in its open position; and

Fig. 4 is a sectional view through a last pin on the jack, and partsassociated therewith, in a plane extending heightwise and laterally ofthe shoe.

Since the invention is herein illustrated as applied to a machine of thecharacter disclosed in the previously mentioned Letters Patent, onlysuch parts as it is necessary to refer to for an understanding of theinvention will be described in detail. The machine is provided with ashoesupporting jack l mounted to swing, prior to the starting of thepower-operation of the machine, from an initial forwardly inclinedwork-receiving position to carry the shoe into position for its heel endto be embraced and clamped by a heel band 2, the lower portion of whichis shown in Fig. 1. It will be understood that associated with the heelband are wipers for wiping the margin of the heel end of the upperinwardly over an insole or heel-seat piece on the last, and a holddowninto engagement with which the heel end of the shoe is carried by upwardmovement of a jack post 3, the wipers and holddown being omitted fromthe present drawings. is provided with a last pin t arranged to enterthe spindle hole in the heel end of the last, this last pin in theconstruction shown being fast in a block 5 (Fig. l) which is mounted ina transverse guideway 6 formed in another block I supported on the upperend of the post 3. A screw 8 extending through a slot 9 in the block 5and threaded at one end in the block 1 retains the block 5 in placewhile permitting it to rock and also to move bodily with the last pin indirections widthwise of the shoe. The block I is mounted in arcuateguideways it in the post 3 for movement about an axis extendinglaterally of the shoe and located substantially at the bottom of theheel end of the shoe. Accordingly the operator, before starting thepower operation of the machine, may by control of the forepart of theshoe and last tip them, together with the last pin, in one direction oranother or move them bodily to the left or the right to position them inproper relation to the lasting instrumentalities. The top of the cone ofthe last when the latter is mounted on the pin 5 rests on a plate l2through which the pin extends, this plate being supported on the block 5and being held thereon by a pair of leaf springs l3 which are fast onthe block and extend into grooves formed. in the opposite sides of theplate. It will be understood,

The jack 1 therefore, that the plate l2 partakes of any of theabove-mentioned positioning movements of the last pin 4 and the lastmounted thereon.

For purposes of the present invention there is provided, in addition tothe main heel band 2, an auxiliary heel band M for clamping the heel endof the upper against the end and side faces of the last when the jack isin its work-receiving position and for holding the upper thus clamped asthe jack is swung to carry the work into the heel band 2. In order thatthe auxiliary heel hand may be maintained in proper clamping relation tothe upper as the work is raised by the post 3 and during any suchtipping or bodily lateral movements of the last as above described, theauxiliary band and the mechanism. forapplying it to the shoe aresupported on the above-mentioned plate I2. To this end, the plate hassecured to it a depending carrier i5 to which a casting I6 is secured bybolts H. The casting I6 is provided at its opposite sides with guidewaysit for a frame l9 which, as viewed from above, is substantially U-shapedwith its two limbs ex-' tending forwardly, this frame being bolted tothe casting HQ with provision for upward or down ward adjustment alongthe guideways I8. The forward end of each limb of the frame H) hasthereon a boss 2t, and hollow pins 2| extending into these bossesprovide a pivotal connection between the frame l9 and asecond somewhatsimilarly shaped frame 22 the forwardly extending limbs of which lie atthe inner sides of the limbs of the frame l9 but are inclined somewhatupwardly toward their rear ends. The frame 22 is provided with anupwardly and forwardly curved lug 23 formed on the middle portion of theweb which joins the rear ends of its limbs, this lug being of a hollowand substantially rectangular shape as viewed from the front (Fig. 2). Apin 24 secured in the opposite sides of the lug 23 provides a pivotalsupport for a depending lever 25, the pin being normally supported at adefinite height, in order to prevent the frame 22 and the lever 25 fromfalling, bya connection hereinafter described between the lug 23 andheel-band'sup porting levers 31.

The depending lever 25 has mounted therein,

approximately midway between its upper and lower ends, a plunger 29which is urged rearwardly by a spring 39 and bears at its rear endagainst a face in on the frame 22, so that the spring tends to swing thelever 25 forwardly about the pin 24'. The lever 25 is swung rearwardlyabout the pin 24 by mechanism hereinafter described, and by suchmovement of the lever the auxiliary heel band M is applied to the shoe.ed in an upstanding ear 33 on the lug 23 a rod 35 which extendswidthwise of the machine, the rod being capable of moving lengthwiserelatively to this ear a short distance determined by flanges For thispurpose there is rotatably mount- 36 formed on the rodat the oppositesides of the ear. The opposite end portions of the rod 35 have right andleft threads, respectively, formed thereon, and these portions of therod extend through correspondingly threaded studs 36 on which aremounted the previously mentioned levers 37 which support the front endsof the auxiliary band l4. By means of a knob 38 the rod 35 may be turnedto cause the upper ends of the levers 31 to approach or separate fromeach other as required by shoes of different widths. The studs 36support the levers3'l substantially midway between the upper and lowerends of the levers, and in order to apply the auxiliary bandv properlyto the shoe, provision is afforded for swinging movements of the leversfirst lengthwise of: theshoe about axes at their lower ends to causetheband to clamp the upper against the endface of the last and thenlaterally of the shoe about the studs 36 to force the forward ends ofthe band inwardly against the sides of the shoe. The lower ends of thelevers are forked and are pivotally connected by pins 40 to the enlargedheads of studs 39 which have hollow portions movable lengthwise and alsorotatable within the previously mentioned hollow pins 2| on the frameI9. Springs 42in the hollow portions of the studs 39-tend to. force thestuds inwardly toward each other. Between the inner ends of the studsand the opposite sides of the lever 25 are links 4| having rounded endsseated in. recesses formed in the studs and the lever. The links-4| arearranged to serve as-a toggle between the'studs 39 and the lever 25, andby the action of the spring 30 on the lever 25 and of the springs 42 onthe studs 39 the parts are normally so positioned that the links4lextend forwardly at a substantial angle to each other. By reason of theresistance of the springs 42 a rearward pull on the lower end of thelever 25 first causes the lever to swing about the inner ends of thelinks 4| as a fulcrum, so that through the pin 24 it swings the frame 22forwardly about the hollow Since this frame is connected to thelevers3'l by the rod 35, this movement of the lever 25 serves to swingthe levers 3! forwardly about the axes of the studs 39 at their lowerends to apply the band |4in clamping relation to the end face of theupper Thereafter, in response to resistance of the shoe to forwardswinging movement of the levers 31, the lever 25 begins to swing aboutthe pin 24 during a continued rearward pull on its lower end andtherefore acts to straighten more or less the toggle provided by thelinks 4| and thus to swing the levers 31 about the studs 36 to force theforward ends of theband inwardly against the sides of the shoe.

The upper ends of the levers 31 are forked and carry pins'44-extendinglengthwise of the shoe and on which are pivotally mounted blocks 48secured to the forward ends of the band l4. This.

band is long enough to extend well forwardly of the heel-breast line ofa large size shoe beyond the portion of the upper clamped by the mainband '2, and the upper edges of the band at its forward ends arearranged to press the upper against the sides of the last almost up tothe edge of the insole or heel-seat piece on the bottom of the last, theframe I9 being adjustable as described to position the band in the mostappropriate relation to shoes having heel ends of different heights. Therear end portion of the band is arranged to extend so far downwardly asto engage the upper close to the top edge of the counter, and thereforeserves to hold this portion of the upper materials against movement awayfrom the end face of the last during the lasting operation. This affordsincreased insurance that during the action of the wipers the wings ofthe counter will not be displaced in a downward direction. The bandconsists of an inner layer 43 of thin flexible leather backed up by alayer 45 of thin resilient metal, the band as a whole, therefore, beingso formed as to accommodate itself readily to the heel ends of lasts ofvarying sizes and shapes. To increase the flexibility of the auxiliaryband, it is so formed as to expose a portion of the upper lying betweenthe; edge of the heelseat and a narrow portion end of the upper near thetop of the counter. In order to prevent the main band 2 from formingcreases in the upper thus exposed by urging it forwardly along the sidesof the last, the aux-.

iliary band is provided with a pair of 'wings 46 extending rearwardlyfrom its front end portions and arranged to be pressedagainst the upperby the main band as the latter closes around the shoe. The metal layer45 of the auxiliary band, moreover, is so shaped as to cause the upperedges of the portions of the band at the sides of the shoe to flaresomewhat outward relatively to the lower edges before the band engagesthe shoe,

as illustrated in Fig.3, and the connections between the band'and thelevers 31 are positioned near the upper edges of the band. By reason ofthis construction the lower edges of the band at thesides oftheshoeengage the upper before the upper edges of the band and the area ofcontact of the band with the sides of the upper progressively spreadstoward the edge of the last bottom as the levers 31 are swung inwardly.This serves to prevent the formation of wrinkles in the sides of theupper and causes the opposite side margins of the upper to extend wellinward over the bottom of the last forwardly of the heel-breast line.The pins 44 which connect the band to the levers 37 may be readilyremovedto permit bands of different lengths to be mounted on theleversfor use on shoes which differ widely in size. The levers 31 during theirswinging movements are further guided and controlled by yokes 41 whichvare formed on the frame 22 and partially embrace the lower arms ofthelevers.

For operating the lever 25 to apply the band I4 to the shoe inthe mannerabove described, there is connected to the lower end of the lever a wire49 whichextends partly around a small pulley 5| mounted on a downwardlyextending portion of the casting l6 and is connected at its lower end toa treadle 52 pivoted on the frame of the machine. It will thus be seenthat the lower end of the lever 25 is swung rearwardly by depression ofthe treadle. In order to hold the band in clamping relation to the upperwhen-the operator releases the treadle 52, there is provided on thelever 25 an abutment 53 which is engaged by a latch 54 formed on a lever55 .pivotally mounted on theframe I9, this lever being controlled by aspring-pressed plunger 56 which tends to swing the latch upwardly butisyieldable to permit the abutment 53 to snap over the latch. There isfurther provided means for withdrawing the latch from the abutment torelease the band-applying mechanism and permit the band to return to itsinitial position when the jack is swung forwardly to its initialposition after the operation of the machine on the shoe. For thispurpose the jack I has fast thereon an arm 51 which supports on itsforward end portion a latch-releasing lever 59 pivotally mounted on apin 5|) on the arm. This lever as shown; has an upwardly and rearwardlycurved arm arranged to engage the lower end of the lever 55 and thus toswing the latch 54 downwardly in re.-' sponse to the forward swingingmovement of the jack. Pivotally mounted on a pin '62 on a shortforwardly extending arm of the lever 59: is a downwardly extendingtubular casing 64 in which is mounted a. plunger 66 engaged at its upperend by a spring 68 in the casing. Slidingly mounted in a forwardlyextending lug 10 on the casing 64 is a rod 12 arranged to bear at itsupper end against the arm 51 and controlledby a of the band extendingcontinuously around'the spring 14 mounted between the lug l and a nut16' on the rod.- It will thus be seen that the spring 14 tends to swingthe casing 64 in a rearward direction, such movement of the casing beinglimited by a stop screw 18 which is threaded in a lug 80 on thecasingand is arranged to engage the arm 51. This screw is so adjusted thatwhen the jack is in its forwardly inclined position the lower end of theplunger 66 lies in front of a plate 82 fast on the frame of the machine.Itv will be understood that as the jack is swung rearwardly the forwardend of the arm 51 swings both rearwardly and upwardly, in which movementof the arm the spring 14 may yield by reason-of engagement of the plate82 with the lower end portion of the plunger 56 until the plunger hasbeen lifted far enough to snap over thetop of the plate. When the jackis swung forwardly after the completion of the lasting operation, thelower end of the plunger 66 is engaged by the top of the plate 82 and bythe action of the plate on the plunger the lever 59 is swung in acounterclockwise direction (Fig. 1), the spring 68 being stronger thanthe spring 14. By this movement the lever 59 operates the lever 55to'cause the latch 54 to release the band-applying mechanism. As thejack nears the end of its forward swinging movement the plunger 66 snapsdownwardly off the plate 82, permitting the parts to assume their normalpositions illustrated in Fig. 1. When the band-applying mechanismis thusreleased by the latch 54 the frame 22 is returned to its initialposition by a springpressed plunger 84 which is mounted in the frame I9and engages a downwardly extending tail portion of the frame 22, and thelever 25 is swung forwardly about the pin 24 by the spring and.

the springs 42.

In the use of the machine equipped with the above-described mechanismthe operator first adjusts the frame l9 upwardly or downwardly, ifnecessary, to position the auxiliary band [4 at the proper height forthe work to be operated upon, and also, if necessary, adjusts theforward ends of the band toward or from each other by turning the rod35. If the machine is to operate on stitchdown shoes of a type in whichthe heel end of the upper is fastened in lasted position to a looseheel-seat piece as distinguished from a complete insole, the operatorpositions such a heel-seat piece on the bottom of the last and assembles.an upper on the last with a counter in its heel-end portion. If heregards it as desirable, before mounting the last on the pin 4, heapplies a pull to the toe end of the upper by means of hand pincers totension the upper somewhat lengthwise of the last and drives a tackthrough the margin of the toe end of the upper to hold the upper in suchtensioned condition. He then mounts the work on the last pin while thejack is in its forwardly inclined position and while the auxiliary heelband occupies the position illustrated by broken lines in Fig. 1. Theoperator next adjusts the extreme heel end of the upper into the desiredposition heightwise of the last and, by means of hand pincers orotherwise, applies an upward pull to the opposite sides of the upperjust in front of the heel-breast line of the shoe to position thoseportions at the proper height and cause them to lie snugly against thesides of the last. While holding the upper in such adjusted relation tothe last the operator depresses the treadle 52 to move the auxiliaryheel band I4 first forwardly lengthwise of the last, and by furtherdepression of the treadle forces the forward end portions of the bandinwardly into clamping relation to the upper at the sides of the last.By its forward movement the band serves to press the upper closelyagainst the heel-end face of the last, especially near the top of thecounter, and to work the upper forwardly along the sides of the heelportion of the last. As the forward end portions of the band are closedinwardly the band engages the sides of the upper first at substantialdistances from the edge of the last bottom and thenprogressively nearerthe last bottom to insure that the upper will be clamped smoothlyagainst the last without objectionable wrinkles.

plying it to the shoe partake of the upward movement of the jack post,since they are supported by the plate l2 on the post, and they alsopartake of such tipping movement of the shoe in one direction oranother, or such bodilylateral movement of the shoe, as the operator mayeffect in the manner hereinbefore described to position the shoe inproper relation to the lasting instrumentalities. It will be understoodthat the auxiliary heel band, in addition to holding the heel end of theupper in proper relation to the last during the movements of the jack,also serves as means for shaping the heel portion of the upperpreliminarily about the last before the main heel band 2 becomeseffective to perfect the shaping of the upper by its further clampingpressure about the heel end of the last. After the work has beenproperly positioned, the operator starts the power operation of themachine and the heelend lasting operation is then performed in themanner characteristic of machines of the illustrated type. When thelasting operation has been completed the jack is permitted to swingforwardly to its initial position, and in this swinging movement of thejack the latch 54 is operatedby the lever 59 torelease the mechanismwhich operatesthe auxiliary heel band and permit this mechanism and theband to return to their starting positions.

While the inventionhas been described more particularly with referenceto the lasting of stitchdown shoes, it is contemplated that it may beused also with beneficial results in the lasting of the heel ends ofshoes of other kinds which have not been previously lasted along thesides' of the shank portion, and that under some conditions, moreover,its use may be beneficial even though the shoes have already been lastedat the shank portion.
